Product Description

LOCTITE® FREKOTE® B-15 is a clear, colorless, one-part, solvent-based polymeric mold sealer formulated for preparing composite and metal molds with micro-porosity, minor surface scratches, or other small imperfections. It forms a base coat that seals the mold surface before application of a compatible FREKOTE® mold release agent. The sealer provides high thermal stability and is formulated to avoid contaminating transfer to molded parts, supporting consistent mold preparation and release-system performance.

Key features

  • Mold-surface sealing: Seals micro-porosity, minor scratches, and small surface imperfections.
  • Composite and metal mold compatibility: Formulated for preparing both composite and metal mold surfaces.
  • Base-coat function: Used with compatible FREKOTE® products to support the mold release system.
  • Non-contaminating transfer: Formulated to avoid transfer of contaminating material to molded parts.
  • High thermal stability: Supports mold preparation for elevated-temperature molding processes.

Applications / Suitable for

  • Preparation and sealing of composite molds
  • Preparation and sealing of metal molds
  • Molds with micro-porosity, minor scratches, or small surface imperfections
  • Base-coat preparation before application of compatible FREKOTE® mold release products
